` TELEPHONE-HOLDER.

Specification of Letters Patent.

Patented J an. 2, 1906.'

To all whom Lr may concern:

Be itV known that I, Louis S. HALLowELL, a citizen of the United States, residing at New York, in the county of New York, State of New York, have invented certain new and useful Improvements in Telephone-Holders, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a telephoneholder, and particularly to a counterbalanced supporting-arm for carrying a telephone and adapted to retain it in any desired position within the arc of the travel of the arm.

The invention has for an object to provide a tubular supporting-arm through which an adjusting-rod passes and is provided with a counterbalancing-spring entirely inclosed and protected therein, while its disposition permits the arm to travel from a vertical plane into a horizontal one.

A further object of the invention is to provide an improved construction of adjustable holding-j aw for retaining the telephone or object supported in position; and another object is to provide a novel construction of base for supporting the parts for pivotal movement and for receiving the strain and weight of the parts in any of its adjusted positions.

Other and further objects and advantages of the invention will be hereinafter set forth and the -novel features thereof defined by the appended claims.

In the drawings, Figure l is a perspective of the invention; Fig. 2, an enlarged detail vertical section,"Fig. 3, a detail perspective of the adjustable the line 4 4 of Fig. 3.

Like letters of reference refer to like parts in the several iigures of the drawings.

The letter A designates a tubular supporting-arm which may be of any desired size or configuration and is preferably provided at its opposite ends with bifurcated lugs at A and A2, the former of which is adapted to support the holder B of any preferred construction,-

as shownl in Fig. l, which is pivotally mounted at B upon the lug A and also provided with a depending pivoting-lug B2, connected with the adjusting-rod C by a curved coupling C', threaded upon the rod. At the opposite end of the tubular supporting-arm the bifurcated lug A2 is pivotally connected with the base D at the point D these lugs A and jaw, and Fig. 4 a section on- A2 being disposed at one side of the longitudinal aXis of the tubular arm and parallel to the rod C, passing therethrough, which permits the rod to have the proper travel for the arm to lie in either a true vertical or a horizontal plane, as shown by dotted lines in Fig. l. The base D is provided with a pivot D2 at its end, which is connected with the curved coupling C2, threaded upon the lower end of the adjusting-rod C. The couplings C C2' permit the use of a straight rod C between the points B2 and D2, which are at the center of the tube A. This base may be mounted by any suitable form of attachment. For instance, for permitting a rotary movement of the entire device the basemay be provided with pivoting-lugs D3, adapted to seat upon a pintle D4, carried by an attaching-plate D5, which may be attached in any desired manner or in any preferred position to a desk, table, or other point of support, as found inost desirable. This plate D5 is provided with a threaded socket D6, into which the angularly-disposed shank D7 of the pintle D4 is r threaded and secured bya lock-nut D8, Fig. 2.

For the purpose of counterbalancing the weight of .the telephone or other object carried by the holder as the same travels downward into a horizontal position a tensionspring A3 is disposed within the tubular arm A and surrounds the adjusting-rod C. This spring bears at one end against an apertured partition-plate A4 within the arm and at the opposite end against an adjustable abutment C3, mounted upon the rod C, which in its adjustment upon said rod will vary the tension of said spring to properly counterbalance the weight of the telephone or other object applied tothe holder.

The invention is adapted for any desired telephone holder; but I have herein illustrated apreferred construction, as shown at E, which comprises the iXed jaws E and the adjustable jaw E2, provided with a shank E3, adapted to enter a channel E4 in the body of the holder. This shank is provided with recesses or sockets therein, adapted to cooperate with a cross pin or screw E, as shown in Fig. 4. It will be obvious that with this construction the jaw may be adjusted to fit the base of any telephone with which it may be desired to use the invention.

For the purpose of relieving the strain and applying it to the base of the holder when the ICO latter is in a horizontal position the curved coupling O2 is provided at its upper end with a plate C4, adapted when the parts are thrown into a substantially horizontal position, as shown by dotted lines in Fig. 1,to engage a curved contact-face C5, which has a bearing thereon to apply the strain directly to the base D of the holder.

In the operation of the invention it will be seen that the tubular supporting-arm is adapted to be attached to a desk, table, or other suitable object, and the counterbalancingspring permits the movement of this arm into any position from a vertical plane to a horizontal plane, while the arm remains at rest when released at any desired point. The pivotal mounting upon the attaching device permits the travel of this arm in a horizontal plane. It will be seen that the construction of the tubular arm entirely incases and protects the tension-spring, thus greatly simplifying and providing a more eHicient construction to avoid the use of parallel arms separated from each other, as in the prior art, While the telephone or other object carried by the holder may be retained in a position above the desk when not in use and instantly brought into the proper plane and position for use when desired, so that the telephone can be used by a person sitting or standing. It will also be observed that in the downward movement of the arm from a vertical toward a horizontal plane the tension upon the spring increases as the point of leverage travels, so that the greatest tension of the spring is exerted to counterbalance the weight of the object carried by the holder when it is in a horizontal position.

This invention is described as a telephoneholder, being particularly adapted for that purpose; but it is capable of application to any desired use, and it will be obvious that changes may be made in the details of construction and configuration without departing from the spirit of the invention as defined by the appended claims.

Having described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is
